Format Description of Spectrum Emission Mask XML Files
The files for importing range settings are in XML format and therefore obey the rules of
the XML standard. Below, the child nodes, attributes, and structure defined for the data
import is described. Build your own XML files according to these conventions because
the R&S FSVA/FSV can only interpret XML files of a known structure. For example
files look in the C:\r_s\instr\sem_std directory.
Figure 3-15: Example Spectrum emission mask standard file (PowerClass_39_43.xml)
Be sure to follow the structure exactly as shown below or else the R&S
FSVA/FSV is
not able to interpret the XML file and error messages are shown on the screen. There-
fore, we recommend you make a copy of an existing file (see Save As Standard soft-
key) and edit the copy of the file.
Alternatively, edit the settings using the "Spectrum Emission Mask" softkey and the
Sweep List dialog box and save the XML file with the Save As Standard softkey after-
wards. This way, no modifications have to be done in the XML file itself.
Basically, the file consists of three elements that can be defined:
●
The "BaseFormat" element
●
The "PowerClass" element
●
The "Range" element
The "BaseFormat" element
It carries information about basic settings. In this element only the "ReferencePower"
child node has any effects on the measurement itself. The other attributes and child
nodes are used to display information about the Spectrum Emission Mask Standard on
the measurement screen. The child nodes and attributes of this element are shown in
Table 3-8.
In the example above (PowerClass_39_43.xml under
C:\r_s\instr\sem_std\WCDMA\3GPP, see Figure 3-15), these attributes are
defined as follows:
●
Standard="W-CDMA 3GPP"
●
LinkDirection="DL"
